Abstract: Based on the actual situation of the Daxing branch line project of the Beijing South-to-North water diversion project, the hydraulic test requirements of large-diameter and long-distance ductile iron water pipelines were introduced in detail. The hydraulic test conditions of large-diameter ductile iron pipe, the division of test sections, the selection of test pressure, test discrimination standards, and the countermeasures of test problems were analyzed and studied respectively, so as to ensure that the hydraulic test results can truly reflect the quality of the project, and then serve as the basis for later project acceptance.
